Syntax Inno Setup - OR, AND

Question

I need to modify the Inno Setup script. But I can’t compile it (every time I compile, I have to wait almost 1 hour to complete the build). I need to know how to write the following expression, which is in the C ++ pseudocode:

if ((A==B) || (A==C))
{
  // do something
}

---

The question is, how should I write this in the Inno Setup script, and if possible, do you know that this scripting language is specific to Inno Setup, or can I find the manual somewhere? On the official website it is very difficult to get what you want in a simple way, it is quite confusing, and I could not find simple examples with OR(examples are very simple).
